- represents the Faraday’s law of electromagnetic induction.
- It states that the magnitude of emf induced in the coil is equal to the rate of change of flux ϕ that linkages with the coil.
- Negative sign represents Lenz’s Law which states that the flux produced opposes the rate of change of flux.
- Lenz’s law of states that the direction of the current induced in a conductor by a changing magnetic field is such that it always opposes the change in magnetic field which produced it.
- Lenz’s law is a based on the law of conservation of energy.
